Is there any method to ignore I2S input on DS90UH925 ?

Hi,

My customer asked us that there is any method to ignore I2S input even though they input I2S signal.

For DS90UH927 and 949, I2S inputs (I2S_WC, I2S_CLK, I2S_Dx) are multiplexed GPIO. And user can set GPIO as both input and output, so when they want to ignore I2S signals, I believe that I can suggest them to set I2S inputs to GPIO input.

 However, only in case of DS90UH925, user can set GPIO as only output, so I can NOT suggest them same method as shown above.

Is there any method to diable/ignore I2S inputs on DS90UH925 ?

Thanks in advance,

Machida
